Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application 1] The present invention relates to a CRT display device for a word processor or the like, and more particularly to a CRT display device capable of displaying split screens.

[Prior art and its problems] When editing a text using a word processor, it is necessary to temporarily change the mode to change the format during input editing or to call up another registered text. A means to replace and display text etc. is required.

If the contents of the currently displayed screen are completely changed, it is impossible to know the connection or correspondence between the two screens, so it is desirable to be able to display multiple screens at the same time. For this purpose, a multi-screen display called multi-window is used, and this temporary display data is superimposed and displayed on the current screen like a window.

However, in the conventional multi-window method, the window is displayed on the screen regardless of the cursor position during editing, which may interfere with the editing input.

[Objective of the Invention 1 This invention was made in order to eliminate the above-mentioned problems, and its purpose is to provide a CRT display device in which a window is displayed in a position that does not interfere with the current text input. do.

[Configuration 1 of the Invention] When a CRT display device of the present invention displays another screen superimposed on a screen displayed on a display device such as a CRT, the above-mentioned other screen is placed at a predetermined position farthest from the cursor position on the screen. It is characterized by displaying a screen.

[Example 1 Embodiments of the present invention will be described below with reference to the drawings.

In this invention, when displaying a window over the currently displayed screen, the screen is divided and the window is displayed with priority from the split screen located farthest from the cursor position currently being input. I try not to interfere with the current text input.

FIG. 3 is a block diagram of a word processor having the above functions. 1 is edited based on the editing memory 2 by an editing control section. 3 is a system program for performing the above editing; 4 is a keyboard device used for manual keying; 5

! In the i-Shushiko Mori 2, 20 is a text buffer that stores text data currently being created, and 21 is a window buffer that stores data to be displayed as a window.
Other text data read from the 70-tubii disk device 5, message display in various formats required for window display, data such as brightness information and inversion information that are display formats, and elephant data for dividing the screen. I remember.

22 includes various buffers, counters, and a control unit for determining the priority display phenomenon as described above.

Screen division control using the above-mentioned circuit configuration will be explained next.

Figure 4 shows a CRT device 1 used for displaying text, etc. of a word processor, where the vertical display size is X, the horizontal display size is Y, and the coordinate position of the cursor 2 in the X-th row and the y-th column. Let it be Xs V.

FIG. 5 shows the CRT device 1 divided into four parts, with the upper right divided screen being the first quadrant [I] and counterclockwise the second quadrant [11] to the fourth quadrant [IV]. Name it. In this way, when the basic number of divisions is 4, the number of windows is up to 3 when overlapping display is not performed, and the priority of the window display quadrant is symmetrical to the quadrant where cursor 2 is located. The quadrant is designated as number 1, the quadrant above or below that quadrant is designated as number 2, and the other quadrants excluding the quadrant where cursor 2 is located are designated as number 3.

As shown in FIG. 5, when the cursor 2 is on the third quadrant EII, the priorities are set in the order of [I], [IV], and [II].

Fig. 6 shows the display of the CRT device 7 divided into six parts.The divided screen on the right end is designated as the first quadrant [1F], and counterclockwise from the second quadrant [IT] to the sixth quadrant [VI]. Name it.

In this way, when the basic number of divisions is 6, the number of windows is up to 5 when overlapping display is not performed, and the priority in this case is from the quadrant furthest from the cursor existence quadrant. establish. For example, you can change the cursor existence phenomenon to [
IV], then [I], [VI], [II], [V
], [111]. or,
When the cursor existence phenomenon is located in the center like [111, m, as a general rule, it should be placed at the right end. If the tenth cursor is at [11], [VI],
Priorities are set in the following order: [I It [v], [IV], [ITI].

Figure 7 shows the cursor presence phenomenon in Figure 5 [111]
Each of the quadrants is further divided into 4. In this way, when the number of basic divisions is 4 and the number of secondary divisions is 4, the number of windows is up to 12 when overlapping display is not performed. , the priority in this case basically follows the priority shown in FIG. 5, and when the cursor 2 is on the quadrant as shown in FIG. 7, the priority is [1,], [L], [I2
], [11]-[IV,].

[IV4], [IV2], [IV3]-[11,1
, [TI 41. [I I2].

The order is [11,].

Furthermore, by repeating this division, it is possible to increase the number of windows.

FIG. 8 shows screen division in the case of superimposed window display, and the priority of the window display phenomenon in this case is the same as that without superimposed display.

If the width of the window to be displayed is not reduced and the width of the window to be displayed is not reduced, the window will not fit in the specified quadrant and will be displayed overflowing into other quadrants, but in this case the priority will be the one displayed later. The windows ■, ■, ■, ■ shown in FIG. 8 are set to be high, and the windows shown in FIG. 8 are displayed in numerical order. In this case as well, the principle is that the cursor does not extend beyond the cursor existence phenomenon.

FIG. 1 is a flowchart showing the process of determining the cursor presence phenomenon in the editing memory 2.

When the number of windows N is input in step S, 1, the process proceeds to step S, 2, and if the number of windows N is 3 or less, the basic division number is set to 4 in step 3.3, and then the process proceeds to step 3.4. to set the number of secondary divisions to 0 and proceed to step 8.5.

On the other hand, if the number of windows N is 4 or more in step 8.2, proceed to step 8.6, and if the number of windows N is 4 or 5, step S, set the basic division number to 6 in step 8.4. If the number of windows N is 6 or more in steps S and 6, the basic division number is set to 4 and the secondary division number is set to 4 in step 8.8, and the process proceeds to step 6.5.

In step 8.5, set the value of A to X/2, set the value of B to Y/2,
Set the value of C to Y/3. The values of X and Y are C
These are the vertical and horizontal display sizes of the RT device 7. Step 8
．． If the number of windows N is 3 or less in step 9, step 8
．． Proceed to step 10. If the ordinate value X of cursor 2 is less than or equal to A, proceed to step 8.11. If it is A or above, step 8
．． Proceed to step 12. In step 5611, cursor 2
If the abscissa value y of [I

If is less than or equal to B, the cursor existence phenomenon is set as the third quadrant [111] in step 8.15, and if it is greater than or equal to B, the cursor existence phenomenon is set as the fourth quadrant [IV] in step 8.16. do.

On the other hand, if the number N of windows is 4 or more in step 8.9, the process proceeds to step 8.17, and if the number N of windows is 6 or more, the process continues to step 8.10, where the number N of winds is 4.
or 5, the same process is performed based on the settings of A=X/2 and C=Y/3, and when the cursor presence phenomenon is determined, the display priority is then set by the editing control unit 1. It is determined.

FIG. 2 is a flowchart showing a process for determining window setting phenomena according to the priority display order.

The priority display quadrant determined in step 8.20 is searched, and in step 8.21, it is checked whether there is a quadrant in which a window is not displayed among the priority display quadrants, and if there is an empty quadrant, step At step 8.22, select the highest priority display quadrant among the burnt and empty quadrants and proceed to step 8.23.
On the other hand, if there is no free quadrant, the lowest priority display quadrant is selected in step 8.24, and the process goes to step 8.23. In step 8.23, the position data of the selected quadrant is stored in the window buffer 21, which previously stores display data corresponding to this priority display quadrant, and in step 8.25, the position data of the selected quadrant is stored in the window buffer 21, which previously stores display data corresponding to this priority display By transferring the data in the buffer 7202P to the display memory location corresponding to the position data and rewriting the data, the data is displayed at a predetermined position in the second window.

In this way, the screen is displayed in a window, and when the predetermined mode is completed, the data on the text buffer 720 is transferred to the display memory section again, and the screen returns to the screen where the original editing process is being performed.

[Effects of the Invention 1] In this invention, when another screen is displayed superimposed on the display screen being edited, the other screen is displayed at the farthest position from the cursor position, which is the input position. It becomes possible to eliminate obstacles to input.
